At burnt mesa pueblo, archaeological studies have used the method of tree-ring dating in an effort to determine when prehistoric
people lived in the pueblo. wood from several excavations gave a mean of (year) 1250 with a standard deviation of 38 years. the
distribution of dates was more or less mound-shaped and symmetric about the mean. use the empirical rule to estimate the following.
(a) a range of years centered about the mean in which about 68% of the data (tree-ring dates) will be found
between
and .. a. d.
(b) a range of years centered about the mean in which about 95% of the data (tree-ring dates) will be found
between
and
a. d.
(c) a range of years centered about the mean in which almost all the data (tree-ring dates) will be found
between
and
a. d.
